I no longer trust WonderFox giveaways.
They had this and another one a couple of years ago. I even left positive comments on GOTD at the time, describing how easy it was to install and register. Then when I went to use the program a month ago, a message popped up "Not registered. Please buy the licence to use."
I checked the other WonderFox software I had, and got the same result.
So don't believe anything they say about "good for lifetime."
